Development of thermoplastic composite rods for the reinforcement of concrete

该项目的目标是开发用于混凝土加固的热塑性复合材料棒。新开发的棒材将比目前使用的热固性基复合材料棒材有许多优点。一个主要的优点是，新的热塑性复合材料棒可以在现场弯曲，而目前使用的热固性基复合材料棒不能在现场弯曲。这种现场可弯曲性使棒材更容易用于建筑、道路、桥梁、公园、大坝等民用基础设施的建设。与目前使用的钢棒相比，使用复合棒材将提供更好的耐腐蚀性优势。钢筋的耐腐蚀性越好，钢筋的寿命就越长。在维修频率方面，节省了大量的经济成本。本项目将要开发的制造技术是拉拔这些热塑性复合材料棒。这是一种低成本的大规模生产技术，可以使新的棒材具有成本竞争力。

The objective of the project is to develop thermoplastic matrix composite rods for the reinforcement of concrete. The newly developed rods will have many advantage over currently used thermoset matrix composite rods. One main advantage is that the new thermoplastic composite rods will be bendable in the field while the currently used thermoset matrix composite rods can not be bendable in the field. This field-bendability allows greater ease in the use of the rods for the construction of civil infrastructures such as buildings, roads, bridges, parkades, dams etc. The use of composite rods will provide the advantage of better corrosion resistance as compared to currently used steel rods. The better corrosion resistance of the reinforcing rods will provide longer life of the reinforcement rods. There is a tremendous economic savings in terms of frequency of repairs. The manufacturing technique to be developed in this project is to pultrude these thermoplastic composite rods. This is a low cost mass production technique, which can make the new rods to be cost competitive.
